A wireless communication terminal for supplying an extended data memory and a controlling method thereof are provided to set a data space sharing function between wireless communication terminals, thereby solving a problem caused by a limited memory capacity of a singular wireless communication terminal. A data providing server(101) provides data. Plural wireless communication terminals(102) are set with a data sharing function for sharing the provided data. A data sharing server(103) receives information on surplus memory size from the terminals(102) to transmit information for enabling the data to be received by being divided according to memory size ratios, to the terminals(102), and controls so that the divided data transmitted to the respective terminals(102) is shared among the terminals(102) according to the information.
